Description

Technical Field

[0001] This utility model belongs to the field of ball valve processing technology, specifically relating to a drilling device for ball valve processing. Background Technology

[0002] In the manufacturing of ball valves, drilling is a crucial process. However, existing drilling equipment for ball valve manufacturing has revealed many significant defects and shortcomings in practical applications.

[0003] In terms of functionality, many existing devices only have a single drilling function. After drilling is completed, if it is necessary to clean impurities inside the hole or polish the surface, the equipment must be changed or additional tools must be used. This not only increases the complexity and time cost of operation, but may also introduce errors due to frequent changes in operation, reducing processing efficiency and product quality consistency.

[0004] To address this, we propose a drilling device for ball valve processing that integrates drilling, impurity removal, and grinding, thereby improving work efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a drilling device for ball valve processing, which integrates drilling, impurity removal and grinding, thereby improving work efficiency.

[0006] The specific technical solution adopted in this utility model is as follows:

[0007] A drilling device for ball valve processing includes a base plate, a connecting plate on the top of the base plate, a top plate on one side of the connecting plate, a fixing component for fixing the workpiece on the top of the base plate, a first telescopic component on the top plate, a circular protective shell on the first telescopic component, a driving component inside the circular protective shell, a cross-shaped connecting block on the driving component, a second telescopic component on the connecting plate, a movable plate on the second telescopic component, and three sets of movable holes on the movable plate. A drilling rod, a cleaning rod, and a grinding rod are respectively installed inside the three sets of movable holes. A connecting plate is installed at the top of each of the drilling rod, the cleaning rod, and the grinding rod. A cross groove matching the cross-shaped connecting block is formed on the connecting plate. A spring is fitted onto each of the drilling rod, the cleaning rod, and the grinding rod, and the spring is located between the connecting plate and the movable plate.

[0008] Furthermore, the fixing assembly includes two symmetrical plates disposed on the top of the base plate, each of the symmetrical plates being provided with a third electric telescopic rod, and the telescopic end of the third electric telescopic rod being fitted with a fixing ring.

[0009] Furthermore, the fixing ring is provided with an anti-slip surface.

[0010] Further, the first telescopic assembly comprises a first electric telescopic rod arranged on the top plate, and a supporting disc is arranged at the telescopic end of the first electric telescopic rod, and the supporting disc is connected with the driving assembly through a connecting rod.

[0011] Further, the second telescopic assembly comprises a second electric telescopic rod fixedly arranged on the connecting plate, and a fixed plate is arranged at the telescopic end of the second electric telescopic rod, and one side of the fixed plate is connected with the movable plate.

[0012] Further, the driving assembly comprises a large gear and eight small gears which are rotationally arranged at the central position inside the circular protective shell, the large gear is engaged with the eight small gears, and a fixed rod is arranged at the bottom of each small gear, the bottom of the fixed rod penetrates out of the circular protective shell and is connected with the cross connecting block, and a motor connected with the circular protective shell is arranged on the large gear.

[0013] The technical effects of the utility model are as follows:

[0014] First, the ball valve workpiece to be processed is placed steadily on the base plate, and the fixed assembly is used to apply fastening force to the ball valve workpiece from different directions and angles to firmly fix it, so that any displacement or shaking of the workpiece in the subsequent machining process can be avoided to the greatest extent, thereby ensuring the precision and quality of machining, then, the first telescopic assembly is started, and the first telescopic assembly starts to stretch and push the circular protective shell to move downward along the vertical direction. The driving assembly located in the circular protective shell starts to operate, drives the cross connecting block to rotate at a constant speed, and when drilling operation is needed, the cross connecting block is accurately clamped with the cross groove on the top connecting disc of the punching rod through precise control. Under the continuous driving of the driving assembly, the rotary motion of the cross connecting block is transmitted to the punching rod, so that the punching rod starts to rotate at a high speed. At the same time, the second telescopic assembly is started and pushes the movable plate to move downward, and the movement of the movable plate extrudes the spring sleeved on the punching rod, so that the spring is in a compressed state. Under the joint action of rotation and downward pressure, the punching rod gradually contacts and penetrates the ball valve workpiece, and accurate drilling operation is realized, after drilling is completed, the first telescopic assembly is retracted, and the circular protective shell is lifted, so that the cross connecting block is separated from the connecting disc at the top of the punching rod. At this time, due to the elastic potential energy accumulated by the spring being compressed before, the spring rebounds rapidly and pushes the connecting disc, so that the punching rod returns to the initial position, next, the second telescopic assembly is started again, and the movable plate is pushed to move horizontally. The movement of the movable plate drives the punching rod, the impurity cleaning rod and the polishing rod to move together until the impurity cleaning rod is accurately located below the cross connecting block. Then, the first telescopic assembly is stretched again, and the cross connecting block is lowered and inserted into the cross groove of the top connecting disc of the impurity cleaning rod. Under the action of the driving assembly, the impurity cleaning rod starts to rotate, and the second telescopic assembly continues to push the movable plate, so that the impurity cleaning rod moves downward and extrudes the spring. Under the joint action of rotation and downward pressure, the impurity cleaning rod penetrates into the hole just drilled, and effectively cleans and removes the impurities generated in the drilling process, after the impurity cleaning work is completed, the first telescopic assembly is retracted again, the circular protective shell is lifted, the cross connecting block is separated from the connecting disc at the top of the impurity cleaning rod, and the spring rebounds to reset the impurity cleaning rod. Then, the second telescopic assembly is started to drive the movable plate to move, so that the polishing rod moves below the cross connecting block, and the first telescopic assembly drives the cross connecting block to be inserted into the cross groove at the top of the polishing rod. The driving assembly drives the polishing rod to rotate, and the second telescopic assembly pushes the movable plate to move downward and extrude the spring, and the polishing rod polishes the inner wall of the hole after drilling in detail to improve the flatness and smoothness of the inner wall of the hole. In the whole working process, through the accurate coordinated action of each assembly, the drilling, impurity cleaning and polishing operations of the ball valve workpiece are completed in turn, which not only improves the machining efficiency, but also ensures the machining quality.
